And Boyle, IMO, is a great presenter, in part because he is so deadpan

I've watched Patrick's videos for enough years that I know he is not, but I still wonder from time to time. His voice is incredibly flat and uniform, he always uses fake backgrounds and there is extremely high use of jump cuts in his edits.

The jump cuts have been there since almost the beginning.

The community noticed he rarely blinks and he ran with the gag and edited all of them out.

I suspect that he at least uses AI for scripts. He tends to repeat the same thing worded slightly differently a few times.
